A rice and wheat harvester threshing drum multi-process automatic welding tool

Abstract

The invention relates to a welding tooling for a threshing cylinder of a rice and wheat harvester, in particular to a fully automatic multi-stage welding tooling for a threshing cylinder of a rice and wheat harvester. The fully automatic multi-stage welding tooling for the threshing cylinder of the rice and wheat harvester provided by the invention has accurate positioning, high work efficiency, prefect functions, long service life, fully automatic clamping of an inner disc, an outer disc and a toothholder, and completion of robot welding. The fully automatic multi-stage welding tooling comprises a base system, an inner disc feeding system, a threshing cylinder rotating system, an outer disc positioning system and a toothholder positioning system. The fully automatic multi-stage welding tooling provided by the invention has the advantages of fully automatic clamping and welding of the inner disc, the outer disc and the tootholder, great reduction in clamping labor intensity, improvement on clamping precision and welding consistency, convenience in operation, improvement on work efficiency, multiple functions, convenience in maintenance, and assurance of safety of staff.

Description

technical field [0001] The invention relates to a welding tool for a threshing drum of a rice and wheat harvester, in particular to a multi-process automatic welding tool for a threshing drum of a rice and wheat harvester. Background technique [0002] At present, when assembling and welding the threshing drum of the rice and wheat harvester, the inner disc is mostly manually installed into the drum body. The positioning of the inner disc, the outer disc, and the tooth seat is not accurate, and the manual welding operation is difficult and the welding consistency is poor. Rarely, after spot welding and positioning the inner disk, outer disk, and tooth seat of the threshing drum of the rice and wheat harvester, the drum is fixed on the simple tooling and welded by a welding robot, so that the welding quality will be improved, but there are also internal defects. Inaccurate positioning of the disc, outer disc, and tooth seat, poor welding consistency, cumbersome and labor-inte...

Problems solved by technology

[0002] At present, when assembling and welding the threshing drum of the rice and wheat harvester, the inner disc is mostly manually installed into the drum body. The positioning of the inner disc, the outer disc and the tooth seat is not accurate. The manual welding operation is difficult and the welding consistency is poor.

Rarely, after spot welding and positioning the inner disk, outer disk, and tooth seat of the threshing drum of the rice and wheat harvester, the drum is fixed on the simple tooling and welded by a welding robot, so that the welding quality will be improved, but there are also internal defects. Inaccurate positioning of the disc, outer disc, and tooth seat, poor welding consistency, cumbersome and labor-intensive clamping of the workpiece, and low efficiency of clamping and welding
